tscircuit

You are helping the user design electronics using tscircuit (React/TypeScript) and the tsci CLI.

When this Skill is active:

• Prefer tscircuit’s documented primitives and CLI behavior. If something is unclear, confirm by:
  • Reading local files in the repo (e.g., tscircuit.config.json, index.circuit.tsx, package.json)
  • Running tsci --help or the specific subcommand’s --help
• Avoid “inventing” JSX props or CLI flags.

Default workflow

1. Clarify requirements (if not already given)

• Board form factor / size constraints
• Power sources and voltage rails
• I/O: connectors, headers, mounting holes, mechanical constraints
• Target manufacturer constraints (trace/space, assembly, supplier)

2. Choose a starting point

• If the repo is not a tscircuit project, recommend:
  • Install CLI, then tsci init to bootstrap a project.
• If a form-factor template is appropriate (Arduino Shield, Raspberry Pi HAT, etc.), prefer @tscircuit/common templates.

3. Find and install components

• Use tsci search "<query>" to discover footprints and tscircuit registry packages.
• Use one of:
  • tsci add <author/pkg> for registry packages (installs @tsci/* packages)
  • tsci import <query> when you need to import a component from JLCPCB or the registry.

4. Write/modify TSX circuit code

• Keep circuits as a default-exported function that returns JSX.
• Use layout props intentionally:
  • PCB: pcbX, pcbY, pcbRotation, layer
  • Schematic: schX, schY, schRotation, schOrientation
• Use <trace /> for connectivity; prefer net connections (net.GND, net.VCC, etc.) for power/ground.

5. Build and iterate

• Run tsci check netlist before tsci check placement and tsci build to catch connectivity issues early.
• Run tsci snapshot to inspect placement before checking routing.
• Run tsci build to compile and validate the circuit.
• DRC (Design Rule Check) errors can often be ignored during development—focus on getting the circuit correct first.
• If routing struggles, reduce density, use <group /> for sub-layouts, or change autorouter settings.
• Use tsci dev only when you need interactive visual feedback (not typical for AI-driven iteration).

6. Validate and export

• Run tsci check netlist before tsci check placement and tsci build when preparing to share/publish.
• Run tsci build (and optionally tsci snapshot) before sharing/publishing.
• Use tsci export for SVG/netlist/DSN/3D/library outputs.
• For manufacturing, obtain fabrication outputs (Gerbers/BOM/PnP) from the export UI after tsci dev.

Safety and non-goals

• Treat electrical safety, regulatory compliance, and manufacturability as user-owned responsibilities.
• Do not publish (tsci push) or place orders unless the user explicitly requests it.
